getting an error in x264 when i'm muxing getting, version, already

andy

2.0 installed already.

- reinstalled megui, same issue

- have not tried reinstalling mp4box but can't find a link to the latest complied package.

it's not a x264 error... but a MeGUI error report.
that is due probably to an outdated mp4box version. updated it: mirror/gpac/dev/MP4Box.7z
please change the thread title.
